Description

[Detailed description of the invention] The present invention relates to the invention of a lattice frame material particularly intended for embankment slopes.

Currently, various lattice frame materials are used, but their assembly requires work at high places or on slopes, and it is not easy to construct the lattice frame along the undulations of the slope, so heavy materials such as secondary concrete products are used. Since then, lattice frame materials made of lightweight materials such as plastic, which are easy to assemble, have come into use.

Looking at the slope on which this lattice frame is being constructed, the main body is sufficiently compacted by mechanical construction, but the soil part is often insufficiently compacted, and there is water permeability between the main body and the soil part. Different soil layers were likely to form, and as a result, pore water pressure was generated in the soil layer due to the infiltration of rainfall, often causing the surface layer to collapse.

If the lattice frame method is used in such a site,
Conventional lattice frames only function to disperse surface water, so that subsurface seepage water often flows around the bottom of the frame, causing the bottom to be gouged out and resulting in collapse.

In addition, on the flange attached to the lattice frame,
As muddy water flows in, mud accumulates, the flanges do not perform their function, and water often overflows the lattice frame and collects at the bottom, causing erosion.

The inventor of the present invention has conducted various studies in order to provide a new lattice frame material that can solve the problems of conventional lattice frames, and has found that the lattice frame material that is currently needed is lightweight and easy to construct. We came to the conclusion that it has excellent drainage capacity, has a large drainage capacity, and has the function of removing subsurface seepage water, and arrived at the present invention.

In other words, the present invention provides a frame material having a fixed length and a hollow rectangular end face shape, which is molded from synthetic resin, with a through hole provided on the entire one side surface, and approximately half of the upper surface and a part of the lower surface of the side surface having the through hole. The lattice frame material is characterized in that a through hole is provided in the lattice frame material, a protruding edge is provided on one side of the upper surface side that does not have the through hole, and the through hole in the side surface is smaller than the through hole in the upper surface and the lower surface.

The configuration of the present invention will be explained below based on the drawings.

It is desirable to use high-density polyethylene as the material for the lattice frame material of the present invention because it is lightweight and has excellent strength.

The shape of the lattice frame material 1 and the functions of each part are as shown in Fig.
The part A is a part that does not have a through hole, and a protruding edge 2, that is, a flange is provided on one side, and the L-shaped part formed by the part A and the protruding edge has the function of draining surface water. ing.

Similarly, the section B, which covers about half of the top surface, has water permeability holes, and this section serves to collect surface water inside the lattice frame, and this section prevents mud from accumulating in the flange. .

The part E, which covers more than half of the bottom surface, and the part F, which covers about half of the sides, have no through holes, and when installed on a slope, these parts become L-shaped and allow water collected inside the lattice frame material to flow. It serves to discharge water to the bottom.

The part D, which covers a part of the lower surface, and the part C, which has through-holes throughout, are the parts that collect subsurface seepage water, and are very important parts of the lattice frame material of the present invention. It is.

The reason why the holes provided on the entire side surface C are smaller than the holes provided on the top and bottom surfaces is that this area is subject to earth pressure, so the holes are made smaller to increase strength. be.

The side surface G may or may not have a through hole, but if it is provided with a through hole, if it is used at the bottom of the slope, water collected from the top of the slope will be discharged to the gutter. It is very effective when

The lattice frame is assembled using the lattice frame materials explained above using a generally known method.
It is assembled in a diagonal lattice shape using K-shaped, T-shaped, L-shaped, and E-shaped joints by inserting the lattice frame material into the joints and connecting them using bolts and nuts provided at the joints.

Once this assembly is complete, the inside of the lattice frame is filled with sandbags or additional soil and planted with vegetation, completing the lattice frame construction method.

As described above, the present invention provides a through hole on the entire side of a frame member molded from synthetic resin and having a hollow rectangular end face shape and has a fixed length, and the through holes are formed in about half of the upper surface and part of the lower surface. The lattice frame material is characterized in that a through hole is provided on the side surface side of the lattice frame, a protruding edge is provided on one side of the upper surface side that does not have the through hole, and the through hole on the side surface is smaller than the through hole on the upper and lower surfaces. Therefore, it is lightweight and easy to assemble, making it ideal for working at heights or on slopes.

In addition, even if muddy water flows through the holes in the upper surface of the lattice frame material, it will flow out through the holes, so mud will not accumulate on the flange and lose its drainage function, and the lattice frame material itself has a large drainage capacity. Therefore, drainage properties are extremely good.

Furthermore, since the through holes are provided on the side and bottom surfaces, it is possible to remove water that seeps below the ground surface, so there is no longer any risk of the grid frame collapsing due to water that seeps below the ground, unlike conventional lattice frames.
